PFC 被動功因:.利用電感、電容於電源端以便將領先或落後之相位做補償,線路架構上較簡單,但其存在體積大、重量重、輸出易因輸入電壓變動而閃爍不穩定。 主動功因:.一般利用市售之IC來達成功率因素修正功能,其原理乃將PFC.IC電路,至於橋式整流器及負載之間,使其電流隨整流後的電壓波型而做調整,其優點為輸出不因輸入電壓變動而改變,但奇線路架構上路較為複雜。 CEX740N(A), CEX10N4, CEX840N (400V/10A) (450V/10A) (500V/8A)
PWM PWM(Pulse Width Modulation)把變流器的輸出電壓斬波成為脈衝,通過改變脈衝的寬度、數量或者分佈規則,以改變輸出電壓的數值和頻率的控制方法。 CEX01N7,CEX04N7, CEX02N7, CEX09N7A , CEX1165 , (700V/0.8A) (700V/4A) (700V/1.9-1.6A) (700V/8A) (600V/10A) CEX1175 (650V/10A) CEX01N6 , (650V/0.9A) CEX02N6, CEX02N6A, CEX04N6, CEX09N6, CEX07N8A (600V /2-1.9A) (650V/1.5-1.3A) (600V/4A) (600V/9A) (800V/6.5A)
